Volumetric Self-Priming Pumps

The volumetric self-priming pump with elastic coupling, range VGA has been designed to load-unload basins, tank-trucks, tanks where is no possible the flooded installations. Reversible and easy to handle, the VGA pumps can prime from negative suction head of max 4 meters without the necessity to feel the priming chamber the first time. Easy to handle, the pumps of this range have strong construction, produced in their components with high thickness to give a product with the maximum reliability. The electric motor is connected to the pump through elastic coupling with spacer, fixed on a carbon steel base plate. Suitable to transfer low viscosity acids and basic liquids, the internal part in contact with liquid are totally built in thermoplastic (PP-PVDF-PVC), the gaskets and the impeller blades are in a suitable material (EPDM). Standard are installed lip seals in EPDM or FPM.
